| At one point in my use of Lantus I realized that it only worked for 19-20 hours and by the time I took the next dose at 24 hours and by the time it started to work my BS was skyrocketing through the night. If you realize that most of us sleep around 8 hours that period of high blood sugars may end up 1/4 of our day. The result for me was a distinct rise in my A1c number. This problem was resolved when my doctor told me to split the dose so that there was always some basal coverage. That worked great but to make everything work my two doses are not the same, 24 am and 18 pm.
The morning highs for you may be a result of the Lantus running out. I have never detected a peak in its action, but splitting the dose would certainly make this less apparent if it does exist. |
